Like all MacBook owners, are you worried that your computer’s battery will wear out too quickly? Today we present to you an application that can make your MacBook battery last longer. Here is how it works.

Know the health of your MacBook battery

With the development of telework, laptops are used more and more on a daily basis. Obviously this intensive use is not without posing some problems. The autonomous operation of these devices makes certain components subject to wear. This is particularly the case with the battery.

This indispensable element is far from being eternal. Over time, the autonomy of laptops decreases due to the wear and tear of the battery. Fortunately, today there are tools that can tell if the battery is badly worn and if it needs to be replaced.

Since the arrival of the 10.15.5 macOS Catalina update, owners of MacBook have a utility for managing battery health. As the name suggests, this tool was designed to extend MacBook battery life by reducing aging.

If you are in the habit of leaving your computer constantly plugged into the AC outlet, the utility will limit the time the battery is at 100% of its charge. This may seem paradoxical and yet the closer the battery gets to 100%, the more it wears out.

The battery health management function is also able to calculate when you need to replace the battery. Note that this operation remains difficult to perform on your own due to the compactness of the MacBook case. Better to turn to a professional.

The battery health management system is enabled by default on your MacBook. However, nothing prevents you from stopping it. Please note that this operation can only be performed on a computer equipped with an Intel chip. On Macs with the Apple M1 chip, the utility cannot be disconnected.

  • Click on the Apple symbol at the top left of the screen
  • Select system preferences from the list
  • Tap Battery then Battery Health
  • Find the line titled Manage battery longevity
  • Uncheck the battery health management box
  • Press OK to validate your choice

Now your battery will charge at its maximum power whatever the conditions of use of your MacBook. It is also advisable to deactivate this feature before a long trip. In this way you will be sure to always benefit from the greatest autonomy.
